This is a chalk bag, a collaboration between Mountain Hardwear and Gravity Research. It cost around 6,000 yen. I'm selling it because I bought a new chalk bag and no longer use this one. It has a zippered pocket on the front, and pockets on the left and right sides that can hold things like black tape. There is no damage, but there are marks from where I had attached some pin badges. I plan to ship it in an A4 envelope via Nekopos (a Japanese delivery service).
